i tried to jailbrake my iPod Touch 1g. I used redsn0w-win_0.7.2. I'm doing everything according to instructions, see "Downloading Data Jailbreak ...", he writes redsn0w done so but nothing happens and next we see the same message, then the iPod restarts and everything is as though nothing had happened. I advise anyone? I tried several times to reinstall, but no change.
